A Physics student wants to investigate the effect of parallel blades on the refraction and linear deviation of light. He uses a glass blade with parallel faces and a refractive index n = 1.5, with a monochromatic light beam incident at an angle of 30° relative to the normal. (a) Determine the angle of refraction of the light beam upon entering the glass blade and calculate the angle of incidence and emergence of the light beam upon exiting the glass blade. (b) Find the linear deviation that occurs to the light beam due to the presence of the glass blade, assuming the thickness of the blade is 3 cm. (c) Explain how the linear deviation found in this experiment can be applied in everyday situations, such as the use of lenses and optical systems.
